Hereinafter, with reference to the accompanying drawings will be described embodiments of the present invention;

First, as shown in FIG. 1, the ozone and sludge treatment system of the plasma generator according to the present invention is characterized by including a plasma generator 100 for generating a plasma.

The plasma generator 100 is a gas state separated into electrons having a negative charge and positively charged ions at an extremely high temperature, and generates a plasma called a 'fourth material state', and maintains the performance and efficiency of the device. In order to prevent corrosion in the apparatus, it is required to remove ozone and sludge which are additionally generated during the generation of plasma.

Accordingly, as shown in FIG. 1, one end of an ozone discharge pipe 110 for discharging ozone generated during plasma generation is connected to an upper end of the plasma generator 100, and the other end of the ozone discharge pipe 110 is formed as follows. 1 is connected to the ejector 120 to allow ozone to be transported into the first ejector 120.

As shown in FIG. 2, the first ejector 120 has a hollow 121 formed therein, and an ozone inlet 122 connected to the other end of the ozone discharge pipe 110 is formed, and the hollow 121 is formed. A spray nozzle 123 is provided toward the apparatus, and a diffuser 128 having a cross-sectional reduction portion 125 and a cross-sectional expansion portion 126 sequentially formed therein to dissolve ozone in water. Ozone remaining inside the hollow 121 by the water injected at a high speed toward the diffuser 128 from 123 enters the cross-sectional reduction portion 125 inside the diffuser 128 together with the water, and reduces the cross-section. It is to be dissolved in the water in the unit 125, the water in the ozone dissolved state is discharged to the outside through the cross-sectional expansion portion 126.

When the ozone inside the hollow 121 enters into the diffuser 128 by the high speed water sprayed from the injection nozzle 123, the inside of the hollow 121 is negative pressure, so that a higher air pressure than the inside of the hollow 121 is generated. Branches suck ozone from the ozone discharge pipe 110, and ozone and water entering the cross-sectional reduction part 125 are mixed as the passage inside the diffuser 128 is narrowed, so that ozone is dissolved in the water. The cross-sectional expansion portion 126 which is sequentially formed with the reduction portion 125 allows the water in the ozone dissolved state to be easily discharged to the outside.

Accordingly, as shown in FIG. 1, one end of the first water supply pipe 130 is connected to the injection nozzle 123 so that water may be supplied into the injection nozzle 123, and to the diffuser 128. One end portion of the first water discharge pipe 140 is connected to allow the water in the ozone dissolved state to be discharged.

At this time, the diffuser 128 is from the injection hole 124 to the cross-sectional reduction portion 125 based on the diameter of the injection hole 124 formed in the injection nozzle 123 to inject water at high speed The distance of the same, that is, characterized in that formed in a 1: 1 ratio, the diameter of the cross-sectional reduction portion 125 based on the diameter of the injection hole 124 is characterized in that the 1: 1.5 ratio. The length of the inclined portion 127 of the cross-sectional expansion portion 126 based on the length of the inner passage of the cross-sectional reduction portion 125 is formed in a 1: 1 ratio. It is characterized in that the inclination angle of 127 is formed from 4 to 6 °.

The above configuration is one of the optimum ratio and the inclination angle for the mixing of ozone and water in the first ejector 120, the inclination angle of the inclined portion 127 as shown in Figure 4 (a) 4 to 6 °, even if water having a certain velocity and flow flows into the cross-sectional extension 126, the water can flow stably, and as the inner passage is expanded, the flow rate decreases but the pressure rises to increase the pressure. 1 to increase the efficiency of the ejector 120.

On the contrary, when the inclination angle of the inclined portion 127 is 7 ° or more, as shown in FIG. 4B, water flows as the wall separation occurs near the inclined portion 127. This becomes unstable and stagnant, causing a loss in pressure increase due to a decrease in the flow rate of water, thereby reducing the efficiency of the first ejector 120.

Therefore, the inclination angle of the inclined portion 127 is preferably 4 to 6 °, most preferably 5 °.

5 (a) and 5 (b) form a distance from the injection hole 124 based on the diameter of the injection hole 124 to the cross-sectional reduction part 125 at a 1: 1 ratio. The diameter of the cross-sectional reduction part 125 based on the diameter of the yarn hole 124 is formed in a ratio of 1: 1.5, and the slope of the cross-sectional extension part 126 based on the length of the passage inside the cross-sectional reduction part 125 is inclined. When the length of the portion 127 is formed in a 1: 1 ratio, and the inclination angle of the inclined portion 127 is formed at 5 °, the cross-sectional reduction portion 125 and the cross-sectional expansion portion 126 of the diffuser 128 are formed. 5 is a photograph of the flow of internal water, and as shown in FIG. 5 (a), in the initial stage when the water and ozone start to mix, the water and ozone are separated from the cross-sectional extension 126 except for the cross-sectional reduction part 125. It can be seen that the mixing proceeds unstable, and as shown in FIG. It is possible to confirm that the mixing of water and ozone proceeds stably in the entire diffuser 128 up to 126.

In addition, a portion of the inner side surface of the diffuser 128 forming the cross-sectional reduction portion 125 is the inside of the cross-sectional reduction portion 125 so that the water and ozone can be stably mixed from the beginning when the water and ozone starts to mix Water flowing along the passage can be configured to form a vortex.

Therefore, a spiral protrusion is formed on the inner side of the cross-sectional reduction part 125 along the longitudinal direction of the cross-sectional reduction part 125 so that water flowing in the cross-sectional reduction part 125 forms a vortex along the protrusion. In addition, a spiral thread is formed along the longitudinal direction of the cross-sectional reduction part 125 to allow the water to form a vortex.

In addition, 0.109g is dissolved in 100g of water at 0 ° C. and 0.057g is dissolved in 100g of water at 20 ° C. The lower the water temperature is, the more the solubility utilizes the characteristics of ozone. In order to raise the pressure, the outer surface of the first water supply pipe 130 may be wrapped with a heating coil configurable of a metal such as copper, and the inner flow path of the first water supply pipe 130 may be heated by the heating coil. Water flowing along the can be heated to increase the solubility of ozone, this configuration is also applicable to the first water discharge pipe 140.

A spray nozzle 163 is provided toward the apparatus, and a diffuser 168 having a cross-sectional reduction portion 165 and a cross-sectional expansion portion 166 sequentially formed therein to dissolve sludge in water. The sludge accumulated in the hollow by the water sprayed at high speed toward the diffuser 168 from the 163 enters the cross-sectional reduction part 165 inside the diffuser 168 together with the water, and the cross-sectional reduction part 165 It is to be dissolved in the water from the inside, and the water of the sludge dissolved state is discharged to the outside through the cross-sectional expansion (166).

Since the second ejector 160 has the same shape and structure as the first ejector 120, the second ejector 160 may be formed by the high speed water sprayed from the injection nozzle 163 of the second ejector 160. When the sludge inside the hollow 161 enters the inside of the diffuser 168 of the second ejector 160, the inside of the hollow 161 is negatively pressured so that the sludge discharge pipe 150 having a higher air pressure than the inside of the hollow 161 is provided. Sludge is sucked from the sludge, and the sludge and water entering the cross-sectional reduction part 165 inside the diffuser 168 are mixed as the passage inside the diffuser 168 becomes narrower, so that the sludge is dissolved in the water, and the cross-sectional reduction part ( 165 and the cross-sectional expansion portion 166 formed sequentially, the water of the sludge is dissolved easily Allow to be discharged to the outside.

Accordingly, as shown in FIG. 1, one end of the second water supply pipe 170 is connected to the injection nozzle 163 of the second ejector 160 so that water may be supplied into the injection nozzle 163. In addition, one end portion of the second water discharge pipe 180 is connected to the diffuser 168 inside the second ejector 160 to discharge water in a state in which the sludge is dissolved.
